The Philippine Atmospheric Geophysical Astronomical Services Administration (PAGASA) said as of 4 p.m., the eye of the storm, now called “Helen,” was spotted 1,390 km east northeast of Casiguran, Aurora.

It said “Helen” has maximum sustained winds of up to 110 kph near the center and gustiness of up to 140 kph, with estimated moderate-to-heavy rains within a 600 km diameter of the storm.

PAGASA weather forecaster Aldzcar Aurelio told CNN Philippines on Saturday that there will be stormy weather in northern Luzon, particularly in Batanes, Cagayan Valley, and the Ilocos region, as well as some parts of central Luzon.

PAGASA expects the storm will move west northwest at 25 kph and will leave the PAR by Wednesday afternoon. Aurelio said “Helen” will make landfall over Taiwan, not Batanes.

The weather bureau has not yet issued a tropical cyclone signal, but advised the public and disaster risk-reduction and management councils to take appropriate actions and watch for the next weather bulletin to be issued at 11 p.m. Saturday.
